Underlying the apparent diversity shown by thousands of mutually incomprehensible languages of the world, there is a remarkable, elegant and principled unity in the way that these languages exploit the phonetic resources of speech. It is these principles that Professor Laver sets out to describe in this major new textbook. Assuming no previous knowledge of the subject, it is designed for readers who wish to pursue the study of phonetics from an initial to an advanced stage, equipping them with the necessary foundations for independent research. The book moves from a discussion of general concepts to a total of eleven chapters on phonetic classification, and it includes discussion of other issues such as the relationship between phonetics and phonology. There are illustrations from over 500 of the world's languages. Principles of Phonetics will be required reading for all serious students of speech and language.* Comprehensive textbook in phonetics, taking students from no knowledge of the subject to an advanced stage * Will also serve as a work of reference for all those working in linguistics who wish to know about phonetics * Laver one of world's leading phoneticians'A treasure house of information on sounds in hundreds of languages ... we can all be grateful that there is now such an up-to-date and comprehensive survey of the production of speech and the variety of sounds that are used in languages of the world.'
